A composite bridge type incorporating corrugated steel webs fits beautifully into the surroundings, as Dole bridge or Maupre viaduct near Charolles do (Figs. 21.1 and 21.2). The innovation of creating a structural element by folding flat a plate into a corrugated shape was developed in France. It allows compliance in compression while maintaining large in-plane shear resistance. This function is ideal in order to enhance the moment capacity of prestressed box girder bridges (Combault et al. 1988, 1993; Capra and Leveille 1998).
